EA cards (such as LSQ1GP12EA and LSQ1TGX1EA) do not support IPv6 features.
Introduction to IPv6 DNS
IPv6 DNS is responsible for translating domain names into IPv6 addresses. Similar to IPv4 DNS, IPv6
DNS involves static domain name resolution and dynamic domain name resolution. The functions and
implementations of the two types of domain name resolution are the same as those of IPv4 DNS. For
details, refer to IPv4 DNS Configuration .

Configuring Static Domain Name Resolution
Configuring static domain name resolution refers to specifying the mappings between host names and
IPv6 addresses. Static domain name resolution allows applications such as Telnet to contact hosts by
using host names instead of IPv6 addresses.
Follow these steps to configure static domain name resolution:
